Chance initially blown, America stepping in, typically (2,5)
I believe the answer is:
as usual
'typically' is the definition.
(I've seen this before)
'chance initially blown america stepping' is the wordplay.
I cannot really understand how this works, but
'america' could be 'us' (United States) and 'us' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for as usual that I've seen before include "Predictably" , "In the customary way" , "In the normal way, habitually" , "Customarily" , "in typical fashion" .)
